TITLE

Linux  of  Linux Kernel  Vulnerability in

DESCRIPTION

In the Linux kernel, the following vulnerability has been resolved: fs: sysfs: Fix reference leak in sysfs_break_active_protection() The sysfs_break_active_protection() routine has an obvious reference leak in its error path. If the call to kernfs_find_and_get() fails then kn will be NULL, so the companion sysfs_unbreak_active_protection() routine won't get called (and would only cause an access violation by trying to dereference kn->parent if it was called). As a result, the reference to kobj acquired at the start of the function will never be released. Fix the leak by adding an explicit kobject_put() call when kn is NULL. Linux of Linux Kernel Exists in unspecified vulnerabilities.Service operation interruption (DoS) It may be in a state. The RUGGEDCOM RST2428P is a Layer 2 Ethernet switch based on the SINEC operating system with up to 28 non-blocking interfaces. SCALANCE X switches are used to connect industrial components such as programmable logic controllers (PLCs) or human-machine interfaces (HMIs). Multiple vulnerabilities in third-party components of Siemens' SINEC OS could allow attackers to gain control of the server. The following advisory data is extracted from: https://access.redhat.com/security/data/csaf/v2/advisories/2024/rhsa-2024_7003.json Red Hat officially shut down their mailing list notifications October 10, 2023.
